如何在NodeJS中正确加密JSON字符串

此数据是加密的json字符串的十六进制字符串。这是通过对称密钥加密的。

我必须以以下方式用密钥加密/解密JSON字符串。我尝试了不同的算法，但没有一个起作用。我尝试了以下代码。

const crypto = require('crypto');
const algorithm = 'aes-256-cbc'

const encryptData = (data, key) => {

    var mykey = crypto.createCipher(algorithm, key);

    var mystr = mykey.update(data, 'utf8', 'hex')
    mystr += mykey.final('hex');
    console.log(mystr);
    return mystr;
}

const decryptData = (encrypted, key) => {

    var mykey = crypto.createDecipher(algorithm, key);
    var mystr = mykey.update(encrypted, 'hex', 'utf8')
    mystr += mykey.final('utf8');

    console.log(mystr);
    return mystr;
}

const crypto = require('crypto'); const text = 'PojmoHD0HNuE/Q+3sKD/ARj86XRYitueWmpjyCuoHuSX71xXlU0hN72wXdrWdt7w//N1BF6GQMLKZIkKXpQ8v18vP1kFG/vO3TpKZRTPhGUyFxE8y1CRIPUJesnbM+Cy3xPegQ3H2wn00YP5f2Dw0uDUHke2MEkCXHYyAgxGqo8='; const key = 'testpassword'; const algorithm = 'aes256' const encryptData = () => { const cipher = crypto.createCipher(algorithm, key); return cipher.update(text, 'utf8', 'hex') + cipher.final('hex'); } const decryptData = (encrypted) => { const decipher = crypto.createDecipher(algorithm, key); return decipher.update(encrypted, 'hex', 'utf8') + decipher.final('utf8'); } const encrypted = encryptData(); const decrypted = decryptData(encrypted);
